Onchdbfhuu Op-Amp Tester Operational Amplifier Test Board Single/Dual/Quad

This circuit board can determine whether an IC is suitable for amplification while also assessing the chip's conversion rate. This T2 operational amplifier test board identifies low-speed chips masquerading as high-speed variants. This operational amplifier test board can be used to test common single-op, dual-op, and quad-op amplifier chips, distinguishing between high-speed and low-speed finished boards. Equipped with LED indicators: For high-speed op-amps, both high-frequency and low-frequency square wave inputs produce normal output, manifested as synchronized illumination of corresponding red and green LEDs-continuous (200kHz) or flashing (10Hz). Test terminals are provided on the board to measure the static current of operational amplifiers under ±5V power supply conditions. The magnitude of static current can reveal certain characteristics of the op-amp and aid in model differentiation.
